Solar LED Street Light Battery Assembly

Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery, gel battery) to store electrical energy, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps.

Solar street lamp system can guarantee the rain weather over 15 days of normal work! Its system composition consists of LED light sources (including the driver), solar panels, battery (including battery insulation box), solar street light controller, street light light pole (including the base) and accessories wire and so on several parts [1].

Solar cell components are usually made of monocrystalline silicon or polysilicon solar cells. LED lamp head generally chooses high power LED light source; Controller is usually placed in a light pole, relating to, the control, overcharge, discharge protection and reverse connect protection, the more advanced controller have the four seasons adjust the lighting time, half power, intelligent charge and discharge functions, etc.; The battery is usually placed underground or there is a special battery incubator, which can be used as a valve control lead acid battery, colloid battery, iron aluminum battery, or lithium battery. The solar lamps are fully automatic and do not need to dig the ditch, but the lamppost needs to be installed on the embedded parts (concrete base).

The LED light source

1. High luminous efficiency, low power consumption, long service life and low working temperature.

2. Strong safety and reliability.

3. Quick reaction, small size and green environment.

4. Under the same brightness, power consumption is one over ten of the incandescent lamp, fluorescent lamp of a third, but life is 50 times of incandescent lamp, fluorescent lamp 20 times, is the incandescent lamp, fluorescent lamp, gas discharge lamp after the fourth generation of lighting products.

5. The invention of single large power ultra bright LED, it is possible that the LED application area will be cross-over to high-efficiency lighting source, and will be one of the greatest inventions since Edison invented the incandescent lamp.

Battery assembly

1) Angle design

For solar cell components to receive as much solar radiation as possible in a year, we need to choose the best inclination for solar cell components.

The study on the optimal tilt Angle of solar cell components is based on different regions in different areas.

2) anti-wind design

In the solar street lamp system, one of the most important structural problems is the design of wind resistance. The anti-wind design is divided into two main parts, one is the resistance design of the battery component bracket, the other is the wind design of the lamp. The following two are analyzed respectively.

The wind design of the solar cell module bracket

According to the technical data of the manufacturer of the battery components, the solar cell components can withstand the upward pressure of 2700Pa. If the wind coefficient is selected as 27m/s (equivalent to 10 typhoons), the wind pressure of the battery module is only 365Pa according to non-viscous fluid mechanics. So, the component itself is perfectly capable of withstanding the 27m/s wind speed without damaging it. Therefore, the key consideration in the design is the connection between the battery module and the lamp bar.

Working principle

Solar street lamp principle of work: during the day under the control of the intelligent controller of solar energy street lamp, solar panels after the illuminate of sunshine, absorb the solar energy light into electrical energy, solar battery components to the battery charge during the day, night batteries to provide electricity to power a LED light source, lighting functions. The dc controller can ensure that the battery pack is not damaged by overcharging or over-discharge, while also equipped with functions such as photo-control, time-control, temperature compensation and lightning protection and anti-polarity protection
